So i checked underneath this morning and still didnt see any new leaks from static sitting in the garage. Popped the Diff fluid add plug and tried to squeeze some fluid in. Only got about 2 oz in and it was cmming back out. Put a bucket under and waited for it to stop dripping and got about 1 oz back out. So doubt it has been the seal leaking. Also looked thru the paperwork and realized that seal was just replaced a year ago. So suspect it had to be oil from somewhere above, but couldn’t get my camera to get a Pic of the OS unit area. It's due for an oil change so have added my mechanic to do a good cleanup of the area and see if he can see where the leak(s) may be.

 

Dealer misdiagnosed my oil leak for being the pressure sensor but it was actually the valley cover leaking in the back. Apparently it’s pretty common too. Many have found their valley cover bolts are only finger tight upon inspection. With the aluminum blocks there is also a porosity issue with the castings that can cause it. That’s Also why the oil pans like to leak on those. With the supercharger on now I won’t be changing that gasket anytime soon.

 

Thats some good info. I know the shop is good and will be able to get it figured out. Just hoping it's a simple issue. I've not had to be adding oil any more than one would expect at 115K miles. But we all know how that story ends often enough. $30.00 part but $3000.00 labor cost! 😫

 

Mech cleaned up area above oil filter (pictured above) & found that the oil cooler junction block gasket (just above oil filter) was leaking. Replaced gasket. Said the area closer up by head/valve cover/etc was all dry. Said to drive it & watch for a while before replacing the skid plate. Hopefully that resolved my issue. Just wanted to update issue.

 

That's awesome. I hope that was the fix and you don't have a lifetime leaker like I do lol.
